Please help and make it accurate.

x = 65.1

Step-by-step explanation:

In relation to the angle, we are given the triangle's adjacent side and hypotenuse. Therefore, we will use the cosine function to determine the value of the hypotenuse:

So, the hypotenuse of the triangle is 65.1 units

i think is g(1)=-1.

hope that i can

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
